I know this is making a leap, but I was just listening to the beach clip 'All My Life', where the chorus goes something like 'I've been waiting for, this moment I'm in'. I know this is one of the songs they had pre-Rubin, and I know it's been stated that none of Rubins material went forward to Eno/Lanois. Maybe someone can tell me if this is a song which was given to Rubin later on, or if they kept it and perhaps presented it to Eno.
I can see Eno taking this song and making it super-atmospheric. From what I can gather from the limited lyrics we've taken from it, the theme seems to match a moment of surrender, that moment Bono sings about in the chorus that he's been waiting for where he can finally let go of whatever insecurity or shelter he's been hiding in. Perhaps Eno has taken this song and reworked it a bit, because I can see him really loving this song for it's depth and potential. However, it does sound like early 2000's U2, but maybe Eno has reworked the sound and feel of it, as well...
Again, just a leap, but the chorus instantly reminded me of the title Eno had thrown out there.
